Currently magnetite iron ore is mined in Minnesota and Michigan in the US Eastern Canada and Northern Sweden Magnetite bearing banded iron formation is currently mined extensively in Brazil which exports significant quantities to Asia and there is a nascent and large magnetite iron ore industry in Australia Direct shipping hematite oresmaintaining iron content in sinter In Table 3 the chemical composition of sinter blends can be seen At 20 addition especially for magnetite concentrate the increase in iron content is significant All LKAB ores however contribute in a positive way regarding iron content A low

Hematite heavy and relatively hard oxide mineral ferric oxide that constitutes the most important iron ore because of its high iron content 70 percent and its abundance Its name is derived from the Greek word for ‘blood ’ in allusion to its red color Learn more about hematite in this articleNov 10 32 Hematite ore is simply mined crushed and after that screened into either lump or fin It is then immediately sold as such The ore has high iron content typically between 56 and 64 Fe Magnetite has higher iron content than hematite But he

‘The replacement of the authigenic magnetite by hematite probably occurred at the same time as the specular hematite that surrounds the dolomite grains’ ‘The claims centre on a mineral with a high iron content called magnetite which is found embedded in the Martian rock in an unusual form’Apr 24 32 Meteorites are heavy due to their high iron content so they tend to feel heavier than most Earth rocks of the same size Magnetite is made up of iron oxide making it opaque and metallic much like a meteorite could appear some other meteorites however can be brown or gray

Karara comprises a large scale long life magnetite orebody amenable to bulk mining and processing Magnetite ore has lower iron content 34 36 Fe than hematite ore 58 64 Fe It must be upgraded by a complex ore treatment process beneficiation to produce a However magnetite attracts premium rates in comparison to its peer haematite because post beneficiation it has a high consistent iron content concentration of 68 and a low associated gangue On the other hand the iron content of high grade haematite may vary between 60 65
